Been doing some research and reading anything I could find on the web, and it seems like I need to move up to the 4.10 gears from 3.45 for my 2.3 Ranger.

It feels very under powered and accelerates horribly slow. I'm needing a better low end acceleration over 2-3 mpg on the highway. I just want to make sure that I have it correct here that 4.10 would be the best choice. My tire size is 225 70 r15 which is stock, and I'll be keeping it thus.

Also, can anyone recommend and a good brand of gears at a decent price?

 

I'm sure 4.10s would help your 2.3 get moving a bit better. It alot of gear for that tire size but if that's what you want go for it. As for brands I would try and find some 4.10s in a junkyard and call it a day.

 

i'd say upgrade to 3.73

you'll maintain your gas mileage and get some more acceleration

i've got 245/70R16's on stock 3.55 gears.....4.10s would put me back in the stock ratio

for your application IMHO it would be overkill

 

So I would want bigger tires for the 4.10s to be more effective? I guess thats the part I dont understand.

 

with the 225's the 4.10 gears would be a little too much.....it would kill your gas mileage

if you stick with 225's.....3.73s would be about right, they wouldn't murder your gas mileage and you would see better acceleration like you want

if in the future you decide to lift your truck and get bigger tires, go with the 4.10s but if you plan on keeping it stock....i'd stick with the 3.73s

 

I agree with Stig. If you are gonna keep the 225's, I would go 3.73's. If you plan on going bigger tire like a 30" or 31", then I would go 4.10. I would just go to the junkyard and pull a rear end. Thats alot easier and probably more cost effective than buying gears and getting them setup right.

 

i've got 3:73s and 255/70r16s. i'm happy with my milage and my acceleration. mind you i also have 1.7L more then you.
